Abstract
Description
Technical Field
[0001] This application relates to the field of cable technology, and more particularly to an oiling device for cable production. Background Technology
[0002] Cables are devices for transmitting electrical energy or signals, typically installed at high altitudes. To ensure their reliability and durability, proper protection is essential. Oiling is a common method of cable protection; by applying grease, cables can be effectively protected against external environmental factors such as moisture, oxidation, and mechanical wear.
[0003] In the existing technology, cable production first involves using a machine to drive several or several groups of monofilaments (at least two in each group) to rotate and twist together to form a cable. During the oiling process, the twisted cable passes through an oil box containing grease. As the machine drives the cable to move relative to the oil box, the cable is coated with grease.
[0004] However, the above-mentioned method of applying oil to the cables resulted in uneven oil application. Utility Model Content
[0005] This application provides an oiling device for cable production, which improves the uniformity of oiling.
[0006] The oiling device for cable production provided in this application includes a base, an oil-holding component, and an oil-scraping component. The oil-holding component is slidably disposed on the base and is used to hold grease. One side of the oil-holding component has a wire inlet hole.
[0007] The oil scraper is rotatably mounted on the oil container, and is positioned opposite to the cable inlet hole. The cable inlet hole and the oil scraper are used for the cable to pass through sequentially.
[0008] The oil scraper has multiple oil scraping sections, each of which is used to scrape oil from each of the individual filaments on the cable.
[0009] In one possible implementation, the oiling device for cable production provided in this application has an arc-shaped groove for scraping oil, and the extension direction of the arc-shaped groove has an angle with the extension direction of the scraping oil.
[0010] In one possible implementation, the oiling device for cable production provided in this application has a wire passage within the oil scraper for the cable to pass through.
[0011] The line passage includes a smooth section and an oil-scraping section, with the oil-scraping part located on the oil-scraping section.
[0012] The smooth section is located on the side of the oil scraper section facing the inlet hole, and the diameter of the smooth section is larger than the diameter of the oil scraper section.
[0013] In one possible implementation, the oiling device for cable production provided in this application further includes a first driving member and a transmission member. The first driving member is disposed on a base and is connected to the oil scraper through the transmission member to drive the oil scraper to rotate.
[0014] In one possible implementation, the oiling device for cable production provided in this application has a connecting member on the oil scraper, and the connecting member rotatably connects the oil scraper and the oil collecting member.
[0015] In one possible implementation, the oiling device for cable production provided in this application has an oil-holding cavity inside the oil-holding component, which is used to hold grease, and the inlet hole and the oil scraper are both connected to the oil-holding cavity.
[0016] In one possible implementation, the oiling device for cable production provided in this application further includes a pressure component disposed within an oil-containing chamber, the pressure component being used to squeeze the grease.
[0017] In one possible implementation, the oiling device for cable production provided in this application includes a pressure assembly comprising a pressure plate and a second drive member disposed on the pressure plate, the pressure plate being positioned above the grease, and the second drive member being used to drive the pressure plate to squeeze the grease.
[0018] In one possible implementation, the oiling device for cable production provided in this application further includes at least one slide rail, which is disposed on a base, and the oil-holding component is slidably connected to the base via the slide rail.
[0019] In one possible implementation, the oiling device for cable production provided in this application has a first limiting member and a second limiting member rotatably connected to the first limiting member on a slide. The second limiting member rotates relative to the first limiting member to abut or dismount from the oil container.
[0020] The oiling device for cable production provided in this application comprises a base, an oil-holding component, and an oil-scraping component. The oil-holding component is slidably mounted on the base and is used to contain grease. One side of the oil-holding component has an inlet hole. The oil-scraping component is rotatably mounted on the oil-holding component, and is positioned opposite to the inlet hole. When an oiling process is required during cable production, the oil-holding component is slid relative to the base, allowing the cable to pass through the inlet hole into the oil-holding component. The cable, once inside, is immersed in grease. As the cable moves relative to the oil-holding component during production, it is coated with grease. The greased cable then passes through the oil-scraping component. The oil-scraping component has multiple scraping sections, each used to scrape grease from individual filaments on the cable. This ensures that the grease thickness on each filament is consistent, improving the uniformity of the grease coating. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0038] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0039] Secondly, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0040] Furthermore, it should be noted that in the description of this application, the terms "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0042] As the background art illustrates, in existing cable production, several or groups of monofilaments (each group containing at least two filaments) are first twisted together by a machine driven to rotate and form a cable. During the oiling process, the twisted cable passes through an oil box containing grease. As the machine drives the cable to move relative to the oil box, the cable is coated with grease. However, the above-mentioned method of oiling cables results in uneven oiling.
[0043] Based on this, the oiling device for cable production provided in this application comprises a base, an oil-holding component, and an oil-scraping component. The oil-holding component is slidably mounted on the base and is used to hold grease. One side of the oil-holding component has an inlet hole. The oil-scraping component is rotatably mounted on the oil-holding component and is positioned opposite to the inlet hole. When an oiling process is required during cable production, the oil-holding component is slid relative to the base so that the cable passes through the inlet hole into the oil-holding component. The cable, once inside the oil-holding component, is immersed in grease. As the cable moves relative to the oil-holding component during production, it is coated with grease. The grease-coated cable then passes through the oil-scraping component. The oil-scraping component has multiple scraping sections, each used to scrape grease from each individual filament of the cable. This ensures that the grease thickness on each filament is consistent, improving the uniformity of the grease coating.
[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0045] Figure 1 This is a schematic diagram of the structure of an oiling device for cable production provided in an embodiment of this application; Figure 2 for Figure 1 A structural diagram from another angle; Figure 3 for Figure 1 Another structural diagram from a different angle; Figure 4 for Figure 1 Enlarged structural diagram of part A.
[0046] Reference Figures 1 to 4 As shown, the oiling device for cable production provided in this application includes a base 100, an oil-holding component 200, and an oil-scraping component 300. The oil-holding component 200 is slidably disposed on the base 100 and is used to hold grease. One side of the oil-holding component 200 has a wire inlet hole 210.
[0047] The oil scraper 300 is rotatably mounted on the oil container 200. The oil scraper 300 is positioned opposite to the cable inlet 210. The cable inlet 210 and the oil scraper 300 are used for the cable to pass through sequentially.
[0048] The oil scraper 300 has multiple oil scraping sections 3121, each of which is used to scrape oil from each filament on the cable.
[0049] It should be noted that during the cable production process, the machine continuously drives the cable to rotate, which not only twists multiple monofilaments together to form a cable, but also helps to evenly distribute the stress inside the cable, reducing the possibility of deformation and twisting.
[0050] The oil container 200 is slidably mounted on the base 100, as shown in the reference. Figure 1 As shown, the oil container 200 can be positioned relative to the base 100 along... Figure 1 The oil container 200 slides in the +X or -X direction as indicated by the middle arrow. Specifically, when an oiling process is required during cable production, the oil container 200 can slide in the +X direction to allow the cable to pass through it; when an oiling process is not required during cable production, the oil container 200 can slide in the -X direction to move away from the cable. Exemplarily, the oil container 200 can be an oil box, oil tank, oil drum, or other oil container; this embodiment does not impose excessive limitations on this.
[0051] Reference Figure 3 As shown, the oil scraper 300 is positioned opposite to the cable inlet 210, and the cable runs along... Figure 3 The cable, indicated by the middle arrow (+Y direction), passes through the inlet hole 210 into the oil container 200. Immersed in grease, the cable moves relative to the oil container 200 during production, thus coating it with grease. The grease-coated cable then exits through the scraper 300. As the cable passes through the scraper 300, it removes excess grease, which is then applied to areas of insufficient grease, ensuring both the thickness and uniformity of the coating.
[0052] By providing multiple oil-scraping sections 3121 within the oil-scraping component 300, each oil-scraping section 3121 is used to scrape oil from each monofilament on the cable. This ensures that the oil coating thickness on each monofilament is consistent, further improving the uniformity of oil coating.
[0053] The oil scraper 300 is rotatably mounted on the oil container 200. In practice, the oil scraper 300 can move along... Figure 1 The rotation in the W direction, as indicated by the middle arrow, further ensures that each oil-scraping part 3121 on the oil-scraping component 300 can scrape oil from each monofilament on the cable.
[0054] It should be noted that, in specific implementation, the number of oil scraping parts 3121 can be determined according to the number of monofilaments on the cable, and the size of the oil scraping parts 3121 can be determined according to the size of the monofilaments and the oil coating thickness. This application embodiment does not impose too many restrictions on this.
[0055] Figure 5 for Figure 4Schematic diagram of the middle oil scraper component; Figure 6 for Figure 5 A schematic diagram of the internal structure.
[0056] In some embodiments, refer to Figure 5 and Figure 6 As shown, the oil scraper 3121 is an arc-shaped groove, and the extension direction of the arc-shaped groove has an angle with the extension direction of the oil scraper 300.
[0057] Understandably, the monofilament has a circular cross-section, and the oil scraper 3121 is designed as an arc-shaped groove to match the outer surface of the monofilament. It should be noted that the dimensions of the arc-shaped groove can be determined based on both the dimensions of the monofilament and the oil coating thickness.
[0058] Furthermore, because the individual filaments on the cable rotate and twist together, there is an angle between each filament and the cable's extension direction. The extension direction of the arc-shaped groove and the extension direction of the oil scraper 300 also have an angle (i.e., Figure 6 The α angle allows each arc-shaped groove to scrape oil from each individual filament on the cable.
[0059] Figure 7 for Figure 3 A schematic diagram of the pressure removal component.
[0060] In some embodiments, refer to Figure 6 and Figure 7 As shown, the oil scraper 300 has a cable passage 310 for the cable to pass through.
[0061] The line passage 310 includes a smooth section 311 and an oil scraping section 312, with the oil scraping part 3121 disposed on the oil scraping section 312.
[0062] The smooth section 311 is located on the side of the oil scraper section 312 facing the inlet hole 210, and the diameter of the smooth section 311 is larger than the diameter of the oil scraper section 312.
[0063] Specifically, by providing a cable passage 310 within the oil scraper 300, the cable can pass through the cable passage 310 and exit from the oil scraper 300. A smooth section 311 is provided on the side of the oil scraper section 312 facing the cable inlet hole 210, providing a transition area before the cable enters the oil scraper section 312, preventing the cable from being directly subjected to the action of the oil scraper section 3121. The diameter of the smooth section 311 is larger than the diameter of the oil scraper section 312, ensuring that sufficient grease adheres to the cable surface and enters the smooth section 311, thereby ensuring the thickness of the grease coating on the cable.
[0064] In some embodiments, refer to Figure 1As shown, the oiling device used in cable production also includes a first driving member 400 and a transmission member 500. The first driving member 400 is disposed on the base 100 and is connected to the oil scraper 300 through the transmission member 500 to drive the oil scraper 300 to rotate.
[0065] Reference Figure 1 As shown, the first driving member 400 is connected to the oil scraper 300 via the transmission member 500. The first driving member 400 can drive the oil scraper 300 relative to the oil collecting member 200 along... Figure 1 The rotation is in the W direction as indicated by the middle arrow. In practice, the rotation speed of the first driving component 400 can be consistent with the production speed of the machine tool, so that each oil scraping part 3121 on the oil scraping component 300 can be aligned with each single wire on the cable to ensure that the oil coating thickness of each single wire is consistent.
[0066] Specifically, the first driving component 400 can be a motor, and the transmission component 500 can be a belt. The motor drives the oil scraper 300 to rotate via the belt. It should be noted that when the oil container 200 slides to any position on the base 100, it can be moved up and down by the lead screw on the motor to loosen or tighten the belt, so that the belt can drive the oil scraper 300 on the oil container 200 to rotate normally.
[0067] It should also be noted that a gear 330 can be installed on the oil scraper 300, and the belt drives the oil scraper 300 to rotate through the gear 330.
[0068] In some embodiments, refer to Figure 1 and Figure 5 As shown, the oil scraper 300 is provided with a connector 320, which rotatably connects the oil scraper 300 and the oil collection component 200.
[0069] Specifically, the connector 320 rotatably connects the oil scraper 300 to the oil container 200, so that the oil scraper 300 can rotate relative to the oil container 200, thereby enabling each oil scraping part 3121 on the oil scraper 300 to be used to scrape oil from each single filament on the cable.
[0070] For example, the connector 320 can be a bearing or other components. This application does not impose excessive limitations on this aspect.
[0071] In some embodiments, refer to Figure 7 As shown, the oil container 200 has an oil-containing cavity 220 for containing grease. The inlet hole 210 and the oil scraper 300 are both connected to the oil-containing cavity 220.
[0072] Understandably, the oil-collecting chamber 220 can accommodate and store grease. The cable inlet 210 and the oil scraper 300 are both connected to the oil-collecting chamber 220. The cable passes through the cable inlet 210 into the oil-collecting chamber 220, is immersed in grease, and then passes out through the oil scraper 300.
[0073] In specific implementation, refer to Figure 3 As shown, baffles 230 can be installed on opposite sides of the oil-collecting component 200, and an oil scraper 300 can be installed on the oil-collecting component 200. The baffles 230 are then installed on the oil-collecting component 200 with screws. Both the baffles 230 and the oil-collecting component 200 are rotatably connected to the oil scraper 300, which facilitates operation and improves installation efficiency. Moreover, in the event that the cable breaks inside the oil-collecting component 200 during production, the baffles 230 can be disassembled to facilitate repair of the broken area.
[0074] It should be noted that, referring to Figure 7 As shown, the oil-containing component 200 can also be provided with an oil injection hole 240, through which grease can be injected into the oil-containing cavity 220 to ensure the continuity of cable production. In specific implementation, a pipe can be connected to the oil injection hole 240 to inject grease into the oil injection hole 240 through the pipe, or other methods can be used to inject grease into the oil injection hole 240. This application embodiment does not impose too many restrictions on this.
[0075] In some embodiments, refer to Figure 3 and Figure 7 As shown, the oiling device used in cable production also includes a pressure component 600, which is disposed in the oil-holding chamber 220 and is used to squeeze the grease.
[0076] It should be noted that the pressure component 600 squeezes the grease, applying pressure to help it penetrate into the tiny gaps and micropores between the individual filaments of the cable, ensuring the reliability of the grease application.
[0077] In some embodiments, refer to Figure 3 As shown, the pressure assembly 600 includes a pressure plate 610 and a second drive member 620 disposed on the pressure plate 610. The pressure plate 610 is located above the grease, and the second drive member 620 is used to drive the pressure plate 610 to squeeze the grease.
[0078] Applying pressure through the pressure plate 610 effectively reduces air bubbles and voids in the grease, allowing it to be fully coated onto the cable surface and the gaps between the individual filaments, ensuring thorough grease application. The grease-coated cable then passes through the grease scraper 300, which removes excess grease to ensure precise, uniform, and consistent grease application.
[0079] By driving the pressure plate 610 through the second driving component 620, the pressure applied to the grease by the pressure plate 610 can be controlled, ensuring that the grease is coated onto the cable with appropriate pressure and flow, thereby ensuring the uniformity of coating and the quality of grease application.
[0080] For example, the second driving component 620 can be a hydraulic cylinder or other mechanical equipment, and the embodiments of this application do not impose too many restrictions on it.
[0081] In some embodiments, refer to Figure 1 As shown, the oiling device used in cable production also includes at least one slide 700, which is disposed on the base 100, and the oil-holding component 200 is slidably connected to the base 100 through the slide 700.
[0082] There is at least one slide rail 700. There can be one or two slide rails 700, and two slide rails 700 can be arranged in parallel. There can also be more than two. This application embodiment does not impose too much restriction on the number of slide rails 700.
[0083] In a practical implementation, the extending direction of the slide rail 700 can be perpendicular to the extending direction of the oil scraper 300, and the extending direction of the slide rail 700 is... Figure 1 As indicated by the middle arrow in the +X or -X direction, the oil-collecting component 200 is slidably connected to the base 100 via the slide rail 700, allowing the oil-collecting component 200 to slide relative to the slide rail 700 in the +X or -X direction. The extension direction of the oil scraper 300 is... Figure 3 As indicated by the middle arrow, the cable can pass through the oil scraper 300 in the +Y direction or -Y direction. Therefore, when an oiling process is required during cable production, the oil container 200 slides in the +X direction to allow the cable to pass through both the oil container 200 and the oil scraper 300; when an oiling process is not required, the oil container 200 slides in the -X direction to keep it away from the cable, thus increasing production speed and saving time.
[0084] In some embodiments, refer to Figure 1 and Figure 4 As shown, the slide 700 is provided with a first limiting member 710 and a second limiting member 720 rotatably connected to the first limiting member 710. The second limiting member 720 rotates relative to the first limiting member 710 to abut or dismount from the oil container 200.
[0085] It should be noted that the first limiting member 710 can be connected to the slide rail 700 by sheet metal parts and screws, or it can be connected to the slide rail 700 by other means. This application embodiment does not impose too many restrictions on this.
[0086] Specifically, the second limiting member 720 rotates relative to the first limiting member 710 in a first direction to abut against the oil container 200, thereby fixing the oil container 200 and preventing it from sliding during the oiling process. After the oiling process is completed, the second limiting member 720 rotates relative to the first limiting member 710 in a second direction (the first direction is opposite to the second direction) to disengage from the oil container 200, allowing the oil container 200 to slide relative to the slide rail 700 for convenient operation.
[0087] Those skilled in the art will understand that the oiling device for cable production provided in this application comprises a base 100, an oil-holding component 200, and an oil-scraping component 300. The oil-holding component 200 is slidably disposed on the base 100 and is used to hold grease. One side of the oil-holding component 200 has an inlet hole 210. The oil-scraping component 300 is rotatably disposed on the oil-holding component 200 and is positioned opposite to the inlet hole 210. When an oiling process is required during cable production, the oil-holding component 200 is slid relative to the base 100 so that the cable passes through the inlet hole 210 into the oil-holding component 200. The cable passing through the oil-holding component 200 is immersed in grease. During the production process, the cable moves relative to the oil-holding component 200, thereby coating the cable with grease. The grease-coated cable then passes through the oil-scraping component 300. The oil scraper 300 has multiple oil scraping sections 3121, each of which is used to scrape oil from each filament on the cable. This ensures that the oil coating thickness on each filament is consistent, thus improving the uniformity of oil coating.
